Okay how many square of toilet paper span your wrist?
The white dial is going to look bigger. Even bigger so, on the bracelet as the BCE is polished. A leather strap might be a little uncomfortable until it breaks in as it will not want to wrap your wrist. The straps do look and feel smaller as they tapper down from 22mm to 20mm on the BCE. So if you want to go for the smallest possible look and feel, Graphite Dial with strap.
Better yet, just get both (Bracelet and Strap) and switch depending on your mood, dress, etc.
Hope this helps.
